Specification of Letters Patent. l Patented Feb, 289 1922 Application filed November 22, 1920. Serial No. 425,928.

To all 'whom 'it may concern:

Be it known that I, PAUL E. HAwKiNsoN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State or' Minnesota, have invented certain new and useful Improvements in Multiple Socket Vvrrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andy use the same.

My invention relates to improvements in wrenches and more particularly to multiple socket wrenches intended for general usek but especially adapted for use in connection with deinountable wheel rims for turning the nuts or bolts of the rim-retaining lugs. is is well known, such nuts or bolts of standard rim-retaining lugs vary as to size and, hence, dili'erent sized wrenches are required for turning the same. tire-repair stations, as well as garages, where a business is made oin4 applying tireequipped demountable rims to wheels .and removing the same therefrom, it is necessary to have a complete set or vplurality of sets oi socket wrenches to lit the nuts or bolts of standard rim-retaining lugs. Such wrenches are each formed with a brace by which they may be operated and they are often misplaced so that considerable time is lost in finding a wrench of the required size and further, as the work of applying and removing demountable rims is to a very large extent done in the sheet the mechanic is often required to make one or more trips into the building to get a wrench of the required size, resulting in considerable loss of time or he must borrow a wrench from the driver of thercar, which is kvery annoying.

To overcome this difficulty, I provide a single brace with a multiplicity of socket wrenches ol' the required sizes, any one` of which socket wrenches may be very quickly brought into an operative position, to lit lthe nuts o1 bolts ol standard rim-retaining lugs or fastening devices.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and detned in the claims.

Referring to the drawings:

F ig. 1 is a perspective view of the invention; and

In tire or Fig. 2 is a view principally in section taken on the line 2 2 of F ig. 1.

The numeral 3 indicates a brace having at one end a swiveled cap or head e and, at the other end, a fork 5. ate or crank vided with a head 7, having portion of the brace is prorotatable hand piece 6. A a multiplicity ofradial arms 8, is rotatably mounted between the prongs of the fork 5 on nut-equipped `bolts 9 secured in aligned bores in the ends of said prongs. Formed on the outer end of each arm 8 is a socket wrench 10, andthe several wrenches 10 are of different sizes.

To hold the head 7 against rotation with one of the wrenches 10 and its arm 8 aligned with the end of the brace 3, having the cap 4, there is provided a lever l1 intermediately fulcrumed to one of the prongs of the fork 5. This inner end of the lever 1.1 is expanded to afforda thumb piece12 and has, at itsV other end, a pair of laterally spaced depending lugs 13, which straddle the prong' of the fork 5 to which said lever is fulcrumed, and also releasably embraces oneA of the Aarms 8.

A leaf spring 14 is anchored to the fork 5 under the lever l1 and yieldingly holds the thumb-pieceequipped end of said lever raised. By pressing downward on the thumb piece 12,k against the tension of the spring 141-, the lugs 13 may be lifted to release the held arm 8 and thereby permit the head 7 to 4be rotated in the fork 4 to bring any one of the'wrenches 10 into an operative position in which it is aligned with said cap-equipped end of the brace 3. "When the required wrench l0 is brought into an operative position, the head 7 isV locked against rotation by releasing the lever 11 to permit the lugs 13 to embrace the arm 8 aligned with the Vfork Obviously, the lugs 13, straddling one of the prongs of the fork 5, are held thereby against lateral movement and, in turn, securely hold the head 7 against pivotal movenient.

rllhe above described invention, has in actual usage, proven highly eieient for the purpose had in view.

What I claim is:

1. A wrench of the kind described comprising a brace having a swiveled cap, a multiple arm head rotatively mounted on the brace, the arms of said head having nut The intermedi- Sockets of different sizes, and means -for locking said head with one of the nut sockets substantially aligned with the cap and with another oi' said nut sockets substantially aligned with that portion of the brace to which it is pivoted.

2. A Wrench of the kind described comprising a brace, a multiple arm head rotatively mounted on the brace, the arms of said head having' nut sockets of different Sizes, and a yielding'ly held lever mounted on the brace and haring a pair of laterally spaced lock lugs embracing the brace and any one of the arms of said head.

8. A Wrench of the kind described co1nprising a brace having` at one endy a swivelled VCap and at the other end a fork, a multiple arm head rotatably mounted in the fork, the arms of said head having nut ifiozeeo socketsof different sizes, and means or'locking said head with one of the nut sockets substantially aligned with the cap and with another' of said nut sockets substantially aligned with the fork;

4. A Wrench of the kind described comprising' a brace having at one end a swivelled cap and at its other end a fork, a multiple arm headl rotatably mounted in the fork, the arms of said head having nut sockets or' different sizes, and aispring held lock lever intermediately fulcrnmed to the fork and having a loch detent engageable with any of the arms oi the head for' holding said head against rotation with one of the nut sockets substantially aligned with the cap. i o

In testimony whereof I al'lix my signature.
